Answer:
<u><em>A </em></u><u><em>quadratic function </em></u><u><em>is a second degree polynomial function. The general form of a quadratic function is this: f (x) = ax2 + bx + c, where a, b, and c are real numbers, and a≠ 0.</em></u>
Divide, the first operation is the parentheses and then division
Answer:
2/9.
Step-by-step explanation:
Perform multiplication across the fractions. C'mon.
Answer: A
Step-by-step explanation:
Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.
We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.
2²+3²=4²
4+9=16
13≠16
We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.
